Specification of Letters Patent.

Application filed. April 1, 1907. Serial No. 365,799.

preferably rolling a number of tubes in suecession over a surface carrying the coating material, the cigarettes being applied at a common entrance point and removed at a common exit point, and being preferably arranged several simultaneously in the space between these two points. Thismethod of' handling and coating the tubes results in a very high output for the machine, since it is working upon several tubes simultaneously.

Certain other advantages are referred to in detail hereinafter.

The accompanying drawings illustrate more or less diagrammatically a process and apparatus according to the invention.

Figure 1 is an elevation, and Fig. 2 a plan with a curved guide hereinafter referred to removed. Fig. 3 is a side elevation of, the feed table and pusher with the latter in a different position from that of Fig. 1. Fig. 4 is a plan of the same parts with the curved guide in place. Fig. 5 is a longitudinal section illustrating the operation of a finger for ejecting the tubes.

Fig. 6 is an endelevation of the same parts.

Referring to the drawings, the paper tubes A, A A A A A &c. are earned. one after the other over a coating surface B, which is preferably a cylindrical surface on a continuously turning shaft 0, and dipping into a vessel D carrying the paraffin or similar material indicated at E, so that the paraffin is continuously taken up upon the cylindrical surface B. The tubes adhere to the coated surface, and are caught between this surface and a concentric curved guide F, sothat' as the surface turns they are rolled between or over the faces of these two members uninterruptedly from the point of entrance to the pomt of exit. As soon as one tube has advanced sufficiently beyond the entrance point, it is followed by another without waiting for the complete operation on the first. This process of applying or maintaining several tubes at once'upon the coating surface, is of great importance as insuring a very large output.

On the shaft C there is preferably mounted also a cylindrical gripping member G having its face striated in axial direction, and having its diameter substantially equal to that of the cylinder B. This gripping cylinder grips between it and the curved guide F the portion of the tube which is not placed upon the coating cylinder and carries it along with the portion which is to be coated.

The tubes are fed to the rolling and coating mechanism by means of a reciprocating pusher H. The ap aratus may be arranged to receive tubes by and or directly from any tube-forming or cigarette-forming machine, the tubes being either empty or full. In the arrangement shown we suppose an endless tube J (either pasted or crimped) to be fed in the direction of the arrow, to be arriving upon a table K, and to be cut off intermittently by any suitable shears and fed forward in cigarette lengths by-the movement of the pusher H immediately after each. length is cut off.

By the rotation of the cylinders B and G each tube which ispushed off the table K is compelled to rotate as it rolls in contact with the cylinders and the guide F, until it arrives at a point where it has made one or more revolutions. It falls then upon a frame consisting of disks L having a number of notches in their periphery, and arranged in positions to receive the tubes without contact with the coated portions. The frame rotates step by step in order to receive the successive cigarettes, and is of such diameter as to carry the tubes until the coating is sufficiently dry, by which time the tubes roll out of the notches into any suitable receptacle. This frame is therefore both a transporter and a drier.

The number of tubes to be subjected to the coating action at one time will depend. upon the diameter of the coating cylinder and the speed of the machine, and'the drying frame will be proportioned accordingly.

The length of the portion of the cigarette tube which shall be coated is determined by the stop M (Fig. 2), which is laterally adj ustable as shown, and which determines the distance to which the tube shall project over the surface of the coating cylinder, this limiting action of the stop Mtaking place before the tubes are carried by the pusher H to the coating cylinder.

A scraper N may be brought into more or less intimate proximity with the cylindrical surface by means of the longitudinal adjustment shown, and may thus serve to regulate the thickness of the coating carried by the cylinder, and consequently the thickness of the coating applied to the tube.

Various driving means may be used for obtaining the several movements described. For example in the machine shown the main driving shaft is indicated at O, and may be the extended shaft of a cigarette machine to which this coating machine is connected. The movement of this shaft is transmitted by means of gears 1 Q to a gear l t carrying a crank pin S connected to a link T carrying at its opposite end the pusher H. The gear U rotates with the gear ll and engages a gear V, upon the shaft W of which is a cam X, which at roper intervals engages a roller Y on the linlf T so as to lift the pusher on its return movement to allow it to pass over the tube A which is upon the table K. From the gear 71 which rotates with the gear V rotation is transmitted to the gear a, and thence from I) to gear 0 upon the shaft C of the coating cylinder.

The shaft d of the drying frame carries ratch et-wheel e, which is engaged by a ratchet f carried upon a lever g, which may be oscillated at the proper moment by any suitable means such as a cam carried on the shaft 0.

In order to insure the detachment of the tubes at the proper point, it is preferable to use a finger h which receives a backward and forward movement of the same frequency as the movement of the pusher and of the drier. lach time that a new pair of notches of the disks L presents itself at the exit point from the coating cylinder, the detaclier or finger 7L is advanced and pushes the linished tube from the cylinder, so that it fallsinto such notches. The pushers H move forward in a substantially straight line from the position of Fig. 1 until they have shifted a tube from A to A, after which they rise through the notches j of the curved guide F and move backward on a higher level so as to avoid striking on their backward move ment the next tube which has taken the position A. At the substantial completion of the backward movement of the pushers they are lowered again to the position of Fig. 1. The tubes are held lightly down upon the table K by means of the springs 7r which are stationary, and alternate in position with the pushers H. The ejecting finger 7t may be conveniently operated by attachment to a lever Z pivoted below the table or base m on which the machine rests (see 5 and 6) and having its lower end oscillated at suitable intervals by a cam 21.
